Product Description

Thermocouple Insulator

In a thermocouple with probes, the thermocouple wires(positive & negative) are usually separated by ceramic insulators from Cold end to the hot end.
The advantage of Ceramic is cost-friendly, high temperature resistant, and easy to produce different sizes.
For example the Alumina ceramic is the most commonly used because it can bear the wide range temperature from -50°C to 1500°C.

When sensing the higher temperature like 1800°C to 2200°C, Alumina ceramic will not work. The pure Hafnium and Zirconium can bear this range, but they can not form a tube to insulate. The problem has been troubling the high-temperature industry for years.

Our Company, DLX, together with our innovation team, finally developed a Zr Ceramic tube that can withstand temperatures over 2000°C after years of continuous study in the field. It can work well with Tungsten Rhenium Thermocouple WRe5/26 for temperatures from 1700°C to 2200°C, such as the glass industry and steel industry. Feel free to contact us for more details.
